As you surmise, this was the first version of crankcase emission control; a
replacement for the "road draft tube" used in previous years. In theory,
instead of being released into the atmosphere, any crankcase fumes would be
directed back into the carburetor intakes and burned. Thereby greatly
reducing hydrocarbon emissions, a major component of smog.

But in the one picture of the engine there appears to be an additional
add-on breather of some sort on the LH (distributor) side of the valve cover???
